The Key to Efficient Facility Operations
In many industries, particularly oil and gas, pharmaceutical and aerospace, having a seal that performs well in low temperatures is crucial. Utilising low-temperature seal products is essential to ensuring the successful operation of these facilities. Without these specifically developed O-rings, the elastomer will lose its flexibility and ultimately fail.
What Causes Seals to Fail at Low Temperatures?
Elastomers used in O-ring technology naturally become stiffer and less elastic as the temperature cools. At certain very low temperatures, they reach what is known as the glass transition (Tg) state. In this state, the material becomes brittle and rigid, making it difficult to maintain an effective seal.
Additionally, materials contract as they cool, causing O-rings to no longer fit correctly. Cold set is another concern, where stresses experienced at higher temperatures are unable to relax at cooler temperatures. Both of these issues are likely to result in leakage and seal failure.
Selecting the Right Low-Temperature Seal
At NES, we have developed distinct and specialised materials that cater to the demands of clients operating low-temperature facilities. Our products are developed for sealing at temperatures as low as -100°C, and we can offer solutions for cryogenic applications functioning down to -250°C.
Our expert team is on hand to assist you in finding a reliable and cost-effective solution for your low-temperature seal requirements. Contact us today to discuss your specific needs.
